As mentioned at http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q184006& Microsoft's KB article 184006, the limit of 124.55GB for FAT32 partition size is a primarily a limitation of Windows 95/98's 16-bit SCANDISK utility. Other DOS versions supporting FAT32 may allow a larger partition size closer to the theoretical ~8TB maximum suggested by FAT32's specifications (maximum of 268,435,445 clusters times 32 Kb cluster size). Windows 2000 and XP can mount and use a FAT32 partition larger than 32GB, but they cannot natively create one, which according to Microsoft is by design.
